Here's the "French" version of it from FCL Style, $995.

Felder Rushing offers the most complete history I've seen. Most references suggest bottle trees began in the African Congo around the 9th Century AD as a means of capturing bad spirits and protecting the home. Felding's research suggests that bottle trees actually originated much earlier and farther North. African Slaves, "imported" to this country, brought this idea with them and the superstitious Southerners (I think mostly Southerners) adopted it. And he features a fabulous passage from Euroa Welty's Livvie short story on bottle trees.
Here is a nice example from At West End, a lovely catalog/website I recently discovered, for $29.
Napa Style has a few options that make use of one's own bottles. First, the plant nanny.
$20 at Napa Style
Not sure how I feel about those.
If you *must* do the whole wine bottle candle thing, this is a better option-
Vino Luminoso from Napa Style, $28.
If perhaps you have just that one special bottle, enlist the help of the Flat Bottle Co.
I'm still not sure I'm entirely convinced. What do you think?
